Don't pull the entire bolt out, there is a wedge in the bottom of the stem that must be loosened before the stem will loosen. thread the bolt back in so the bolt head is about 1/2" above the stem and tap the bolt.. If that loosens but the stem won't come out then there is some corrosion problem. I don't recommend whacking the crap out of anything with any kind of hammer rubber or otherwise.
